...Today in metro Denver weather history...

22-23 In 1936...heavy snowfall of 7.7 inches was measured in
        downtown Denver.  The heavy wet snowfall formed a thick
        coating of snow on trees and shrubs...but caused little
        damage.  North winds were sustained to 15 mph.
      In 1984...around a half foot of new snow fell across metro
        Denver...causing flight delays at Stapleton International
        Airport where snowfall totaled 6.0 inches and north winds
        gusted to 31 mph.  Up to a foot of snow fell in the
        foothills.  Icy roads produced numerous traffic accidents.
      In 2011...Strong bora winds developed along the Front Range
        following the passage of a storm system. Peak wind gusts
        included: 87 mph at the National Wind Technology Center;

        Range Airport in Broomfield; 71 mph at Longmont; and 64

        Airport...a peak wind gust of 48 mph from the west was
        observed on the 22nd.
      In 2013...A wet early spring snowstorm brought heavy snow to
        parts of the Front Range Foothills and Urban Corridor.  The
        heaviest snowfall occurred near the Front Range Foothills
        and Palmer Divide. Near blizzard conditions forced the
        closure of Interstate 70 east of Denver.  In the foothills...
        storm totals included: 14.5 inches near Conifer; 14 inches
        just southwest of Eldorado Springs and Intercanyon; 13
        inches near Indian Hills; 12.5 inches near Pinecliffe;
        11.5 inches near Golden; 11 inches near Jamestown and
        Roxborough; 10.5 inches near Brookvale and 10 inches at

        record in Denver for the date. In addition...a peak wind
        gust to 33 mph was observed from the east on the 22nd with
        a gust to 30 mph from the north on the 23rd.
22-24 In 1965...a vigorous cold front swept across metro Denver
        late on the afternoon of the 22nd with east-northeast
        winds gusting to 38 mph causing some blowing dust.
        Snowfall from the storm totaled 4.4 inches at Stapleton
        International Airport.  Temperatures on the 22nd dropped
        from a maximum of 63 degrees to 18 degrees in just 10 hours
        and dipped to 3 degrees below zero on the morning of the
        24th.  Maximum temperatures warmed to only 19 degrees on

      In 1957...strong north winds gusting to 62 mph reduced the
        visibility at times to 1 mile in blowing dust at Stapleton
        Airport as metro Denver dodged a major spring storm...
        which produced heavy rain...snow...wind...and dust over
        eastern Colorado on the 22nd through the 25th.  Snow
        drifted to 15-foot depths in some areas.  All traffic
        was blocked...power lines were downed...and livestock and

        Stapleton International Airport.

        27 mph overnight.
      In 1990...several hours of freezing drizzle covered roadways
        with a thin layer of "black ice" which caused nearly 100
        traffic accidents across metro Denver.  In Boulder...snow
        and freezing rain caused numerous accidents and brief power
        outages.  Snow in Boulder ranged from an inch east of town
        to 4 to 5 inches near Table Mesa.  At times thunder was
        heard during the snow.  Snowfall totaled only 0.6 inch
        at Stapleton International Airport where northwest winds

      In 1995...high winds developed late on the 23rd and continued

        at Nederland in the foothills.  Across metro Denver...
        snowfall ranged from 4 to 8 inches.  At the site of the

        North winds gusted to 34 mph at Denver International
        Airport.  As the storm moved east on the 24th and 25th...

      In 2010...a powerful spring snowstorm swept across northern
        Colorado.  The heaviest snowfall occurred in and near the
        Front Range Foothills and deep upslope developed. The

        caused 36500 electrical outages throughout Denver and the
        surrounding metro area.  Power outages also occurred in
        Douglas and Elbert Counties.  In addition...approximately
        5 thousand travelers were stranded at Denver International
